Die for detecting stimulated battery

Abstract

The invention discloses a die for detecting a stimulated battery. A test monomer is arranged on a lower body of the die; an upper body of the die is arranged on the test monomer; and the upper body and the lower body of the die are connected together to form a whole body through a hoop. According to the die, each part is machined independently, so that the precision and perpendicularity can be guaranteed; an insulated sealing ring and a universal guide disc are provided for buffering, so that the uniformity can be guaranteed, the interchangeability is high, and the cost is low; battery pole piece carriers are independent of each other and are molded at one time by using a die, so that the machining precision is high, the die is conveniently cleaned and suitable for batch detection in a pipeline mode, and the cleaning cost is low; and thread machining, mechanical twisting and the like are not required for machining the die, so that every two machining surfaces are in contact with each other through surfaces, and battery pole pieces are stressed uniformly in the die, and the consistency and success rate of batteries are greatly improved. The die is simple in structure, convenient to operate, easy to use, high in efficiency and reusable, materials are saved, and the success rate of manufactured batteries reaches 99.7 percent.

Description

Technical field [0001] The invention relates to a battery testing mold, in particular to a simulated battery testing mold. Background technique [0002] At present, the commonly used test method for battery electrode materials is to make button-type simulated batteries for testing. Due to the processing accuracy of button-type simulated batteries and the loss of sealing molds, the yield rate will drop significantly over time, and the processing cost of molds is high. Economically uneconomical. Later, someone designed different forms of battery testing molds, some of which are threaded sealing modes. The machining accuracy of the end face and the thread is difficult to achieve. Since the perpendicularity and end face finish cannot be guaranteed, the yield is low and the interchangeability is poor. Some parts are fastened by screws. Due to the uneven force applied in all directions, the battery pole pieces receive uneven force and the charge and discharge are uneven. At the same ...

AI Technical Summary

Problems solved by technology

Later, some people designed different forms of battery testing molds, some of which were thread sealing models, and the processing accuracy of the end face and thread was difficult to achieve. Since the verticality and end surface finish could not be guaranteed, the yield rate was low and the interchangeability was poor.

Some parts are fastened with screws. Due to the uneven force in all directions, the battery pole pieces are unevenly stressed, and the charge and discharge are also uneven.

At the same time, most of the pole pieces mentioned above are directly placed in the mold, which is extremely inconvenient for cleaning after use, with high cost and very low efficiency.
